  • Coupler and developer components are also referred to as oxidation dye precursors.
  • the developer components are usually primary aromatic amines having a further free or substituted hydroxy or amino group in para or ortho position, diaminopyridine derivatives, heterocyclic hydrazones, 4-aminopyrazolone derivatives and 2,4,5,6-tetraaminopyrimidine and derivatives thereof used.
  • m-phenylenediamine derivatives naphthols, resorcinol and resorcinol derivatives, pyrazolones, m-aminophenols and substituted pyridine derivatives are generally used.

  • oxidation dyes Although intensive dyeings with good fastness properties can be obtained with oxidation dyes, the development of the color is generally carried out under the influence of oxidizing agents such. H 2 O 2 , which in some cases may result in damage to the fiber. Furthermore, some oxidation dye precursors or certain mixtures of oxidation dye precursors can sometimes have a sensitizing effect on persons with sensitive skin. Direct dyes are applied under gentler conditions, but their disadvantage lies in the fact that the dyes often have only insufficient fastness properties.
  • the colorants must have no or only a very low sensitizing potential and may under no circumstances be mutagenic.

  • the range of commercially available hair colors contains not only the luminous fashion tones but also a large variety of natural tones, which in particular encompass a wide range of brown shades. Especially for covering the gray hair and restoring the original hair color, these natural tones are important.
  • the production of a brown shade can be achieved by blending different bright shades. It is necessary to use yellow component dyes, red component dyes and blue component dyes together. Due to this mixing procedure, the presence of a large number of dye components in the colorant is unavoidable. Often associated with this are application disadvantages such as, for example, a different absorption capacity of the numerous coloring constituents on differently damaged parts of the hair and a resulting inconsistent color result. Also, a nuance due to different good washing or light fastness of the different dyes used over time may be subject to color shifts that are not desired by the consumer.
